Abstract

A method for treating wastes, such as domestic wastes, industrial wastes and similar, the wastes passing several treatment steps and being thereafter separated in various fractions, characterized in that it consists of at least the following steps: a coarse crossing of the received waste materials; a heavy rejects separation of the waste materials in an aqueous phase and a removal of the rejects for further treatments; a grinding of the accepts from the heavy rejects separation and a transport of the ground materials and the fluid to a pulper; a dissolving of these materials in the pulper with a simultaneous, at least periodic grinding; a separation of the suspension completely treated in the pulper into various fractions; and a transport and a further treatment of the created fractions. The invention also relates to a device for performing the method. By means of the invention, a more effective handling of wastes is achieved and also, a large portion of heavy components are early removed from the process and a hawser-like formation is avoided of string-like components.

Description

10 40 507 087 behandlade tross- eller repartade bildningar. De beståndsdelar det härvid är fråga om är bl. a. strumpbyxor och plastsnören. 10 40 507 087 treated faith or repaired formations. The ingredients this is a matter of, among other things. a. tights and plastic cords.

Det skall vidare nämnas att den före pulpern anordnade tung- rejektsepareringen medför effektivare behandling i pulpern av i avfallsmaterialet förekommande fiberinnehàllande beståndsdelar, samt effektivare malning av pulperinnehållet, eftersom be- lastningen i malsteget reduceras.It should also be mentioned that the tongue arranged before the pulper the rejection separation leads to more efficient treatment in the pulp of i fiber-containing constituents present in the waste material, and more efficient grinding of the pulp content, since the loading in the milling step is reduced.

Genom särdragen i patentkravet 1 erhålls nu efter pulpern en làtthanterlig suspension, vilken ytterligare kan uppdelas i ett önskat antal fraktioner. I pulpern sker för övrigt en sådan behandling att sammansatta material av t ex papper och plast separeras och därigenom friläggning möjliggörs av i avfallsmas- san ingående fibrer.Due to the features of claim 1, one is now obtained after the pulper easy-to-handle suspension, which can be further divided into one desired number of fractions. Incidentally, this happens in the pulp treatment of composite materials of eg paper and plastic separated and thereby enable disclosure in the waste mass san constituent fibers.

Genom att den initiala sönderdelningen sker genom sönderrivning eller -skärning tillförsäkras att endast en grov sönderdelning sker, t ex av plastsoppásar, så att i det efterföljande tung- rejektsepareringssteget kan bortsepareras glasflaskor, glas- burkar och metallbitar. Typiskt bortsepareras en mycket stor andel av de tyngre beståndsdelarna i detta första avskiljnings- steg, och det kan förväntas att de flesta tungmetallhalterna i en resulterande fraktion, vilken är lämpad för bränsle, härige- nom i ett normalfall reduceras med åtminstone 50 - 70%.Because the initial decomposition takes place by tearing or cutting is ensured that only a coarse decomposition takes place, for example by plastic bags, so that in the subsequent the glass separation step can be separated glass bottles, glass jars and pieces of metal. Typically a very large one is separated proportion of the heavier constituents of this first separation steps, and it can be expected that most heavy metal concentrations in a resulting fraction, which is suitable for fuel, in a normal case is reduced by at least 50 - 70%.

Genom att målningen av pulperinnehållet sker genom cirkulation därav i en malande pump åstadkoms en ändamålsenlig lösning, vilken effektivt kan behandla materialet för undvikande av ihoptvinning av snörartade beståndsdelar.By the painting of the pulp content takes place by circulation thereof in a grinding pump an appropriate solution is obtained, which can effectively treat the material to avoid recovery of snow-like constituents.

Genom att pH i pulpern modifieras till mellan 4,5 och 5 förbättras den efterföljande avvattningen samt underlättas upp- lösning av i pappersbestàndsdelarnas bestrykningslera, varvid askhalten i det resulterande bränslet minskas.By modifying the pH of the pulp to between 4.5 and 5 the subsequent dewatering is improved and the solution of in the coating clay of the paper constituents, wherein the ash content of the resulting fuel is reduced.

Fördelar uppnås vid anordningar enligt patentkraven 6 - 9 i motsvarighet till relaterande förfarandekrav.Advantages are obtained with devices according to claims 6 - 9 i equivalent to related procedural requirements.

Uppfinningen skall nu närmare beskrivas mot bakgrund av ett utföringsexempel och med ledning av bifogade ritningar, på lO l5 al» C) vilka: Fig 1 visar ett schematiskt flödesschema över en avfalls- behandlingsanläggning enligt uppfinningen, Fig 2 visar schematiskt en anläggning för plasttvätt, och Fig 3 visar en anläggning för tungrejekthantering.The invention will now be described in more detail in the light of a exemplary embodiments and with reference to the accompanying drawings, on lO l5 al » C) which: Fig. 1 shows a schematic flow diagram of a waste treatment plant according to the invention, Fig. 2 schematically shows a plant for plastic washing, and Fig. 3 shows a plant for heavy-duty handling.

Det i fig 1 visade flödesschemat utgår från en mottagnings- station 1 för avfall såsom hushållssopor, industriavfall eller dylikt. Det mottagna avfallet förs via en sönderdelare 2, som grovt river eller skär sönder soporna och ett mellanlager 3 till en förseparator 4, i vilken tungrejektseparering sker i vattenfas. Rejekt utleds i enlighet med 5 i figuren. Acceptet från förseparatorn 4 genomgår åtminstone 1 malsteg vid 6 och tillförs tillsammans med vatten från en vattentank 7 via en avfallsbehållare 8 till en pulper 9. Denna pulper 9 bearbetar avfallsmassan så att en långtgående separering sker av samman- satta material och friläggning sker av i massan innehållna fibrer.The flow chart shown in Fig. 1 is based on a receiving station 1 for waste such as household waste, industrial waste or such. The received waste is transported via a decomposer 2, which roughly tear or shred the garbage and an intermediate layer 3 to a pre-separator 4, in which heavy object separation takes place in aqueous phase. Reject is derived in accordance with 5 in the figure. Accepted from the pre-separator 4 undergoes at least 1 milling step at 6 and supplied together with water from a water tank 7 via a waste container 8 to a pulper 9. This pulper 9 processes the waste mass so that a far-reaching separation takes place of the set materials and exposure takes place in the mass contained fibers.

Till pulpern är kopplad en cirkulationsledning 11 med en malande pump 10, vilken är så utformad att passage av pulper- materialet genom denna tillförsäkrar att uppbyggnad av rep- eller trossartade bildningar av i materialet förevarande snörartade beståndsdelar förhindras. Pulpern uppvisar även en anordning för bortledning av ytterligare tungrejekt vid 12. Det i pulpern färdigbehandlade materialet leds, med användning av den malande pumpen 10, vidare till en silerianordning, vilken i det visade exemplet är uppdelat i tre processteg, nämligen, en grovsil 14, ett cyklonbatteri 16 och en avvattningsskruv 18.A circulation line 11 with one is connected to the pulper grinding pump 10, which is so designed that the passage of pulper the material through this ensures that the construction of or faith-like formations of the present material snowy constituents are prevented. The pulper also has one device for discharging additional heavy objects at 12. It in the pulp the finished material is led, using the grinding pump 10, further to a silage device, which in the example shown is divided into three process steps, namely, one coarse screen 14, a cyclone battery 16 and a drainage screw 18.

För effektiv behandling i cyklonbatteriet är suspensionen däri spådd till en koncentration av ca 1% och avvattningsskruven förtjockar suspensionen till ca 4%.For effective treatment in the cyclone battery, the suspension is therein predicted to a concentration of about 1% and the drainage screw thickens the suspension to about 4%.

Den därvid erhållna suspensionen tillförs ett avsugningsfilter vid 20 och därifrån till en torkanordning 23. I det fall det torkade materialet skall utnyttjas som bränsle, sker pellete- ring i en pelleteringsanläggning 24, varefter resulterande l0 507 087 pellets överförs till en bränslesilo 25.The suspension thus obtained is fed to a suction filter at 20 and thence to a drying device 23. In that case dried material is to be used as fuel, pelletizing takes place ring in a pelletizing plant 24, after which the resultant l0 507 087 pellets are transferred to a fuel silo 25.

Av fig 2 framgår schematiskt en utrustning för borttvättning av plaster från materialet, varvid det inkommande rejektmaterialet från grovsilen 14 (fig l) intas (I) i anläggningen via en kvarn K såsom en skivkvarn. I anläggningens första steg 26 avskiljs sten, grus, glas och liknande tunga föremål, vilka behandlas i en raffinör R och tillförs anläggningens andra steg 27. I detta andra steg sker även ytavskrap vid 28 av lättplast samt uttag av tungrejekt vid 29. I anläggningens tredje steg 30 avskiljs tungplast vid 31, varefter acceptet 32 från denna anläggning återförs till pulpern 9 (fig l).Fig. 2 schematically shows an equipment for washing off plastics from the material, the incoming reject material from the coarse screen 14 (Fig. 1) is taken (I) into the plant via a mill K such as a disc mill. In the first step 26 of the plant is separated stone, gravel, glass and similar heavy objects, which are treated in a refiner R and added to the plant's second stage 27. In this second steps are also surface scraping at 28 of light plastic and sockets of heavy objects at 29. In the third stage 30 of the plant is separated heavy plastic at 31, after which acceptance 32 from this facility returned to the pulper 9 (Fig. 1).

Av fig 3 framgår schematiskt tungrejekthanteringen, varvid rejekt från förseparatorn 4 och pulpern 9 tillförs vid I2 en finkvarn 33 tillsammans med från en tumlare 35 efter åter- vinning av magnetiska metaller vid 36 kvarvarande material. I tumlaren 35, vilken utgörs av en delvis vattenfylld roterande trumma, åstadkoms en ytterligare uppdelning samt upplösning av organiskt material. Efter finkvarnen 33 tillförs detta material till en flotationsanläggning 34 för sedimentering och flota- tion. Acceptet, vilket i detta fall är kvarvarande organiskt material, återförs via 37 till processen via kvarnen före pulpern 9. Rejektet som är sammansatt av glas, grus, sten, samt metaller, tillföres en anläggning för återvinning av såväl magnetiska (MM) som omagnetiska (OM) metallpartiklar, varefter återstoden efter avvattning AV kan utnyttjas såsom t ex fyll- nadsmassa.Fig. 3 schematically shows the heavy-duty handling, wherein rejects from the pre-separator 4 and the pulper 9 are supplied at I2 a fine mill 33 together with from a porpoise 35 after return recovery of magnetic metals in 36 remaining materials. IN the tumbler 35, which consists of a partially water-filled rotary drum, a further division and dissolution of organic material. After the fine mill 33 this material is added to a flotation plant 34 for sedimentation and flotation tion. Acceptance, which in this case remains organic material, is returned via 37 to the process via the mill before pulpern 9. The reject which is composed of glass, gravel, stone, and metals, is added to a plant for the recycling of as well magnetic (MM) as non-magnetic (OM) metal particles, after which the residue after dewatering OF can be used as e.g. nadsmassa.

Uppfinningen begränsas endast av vad som anges i de efter- följande kraven och det ovanstående är endast att betrakta som et utföringsexempel. Sålunda kan det i de självständiga kraven angivna förfarandet utnyttjas utan plasttvätten och tungrejekt- hanteringen enligt ovan.The invention is limited only by what is stated in the following the following requirements and the above are to be considered only as an embodiment. Thus, it can in the independent requirements specified procedure is used without the plastic wash and heavy-duty handling as above.
